Description and Introduction

Divide-By-Twelve Decade Counter The SN74LS92NSR is a 4-bit ripple counter with a divide-by-2 section and a divide-by-6 section.  

### **Manufacturer Specifications:**  
- **Manufacturer:** Texas Instruments  
- **Logic Family:** LS (Low-Power Schottky)  
- **Function:** Counter/Divider  
- **Counting Sequence:** Divide-by-2 and Divide-by-6 (combined for divide-by-12)  
- **Number of Bits:** 4  
- **Supply Voltage Range:** 4.75V to 5.25V  
- **Operating Temperature Range:** 0°C to +70°C  
- **Package / Case:** SOIC-14  
- **Mounting Type:** Surface Mount  

### **Descriptions:**  
- The SN74LS92NSR is a ripple counter that consists of a divide-by-2 and a divide-by-6 section.  
- It can be used as a divide-by-12 counter by connecting the output of the divide-by-2 section to the input of the divide-by-6 section.  
- The counter resets to zero when both Reset inputs (R1 and R2) are high.  

### **Features:**  
- **High-Speed Operation:** Typical propagation delay of 15ns.  
- **Low Power Consumption:** 45mW typical power dissipation.  
- **Schottky-Clamped Inputs:** Ensures high noise immunity.  
- **Wide Operating Voltage Range:** 4.75V to 5.25V.  
- **Standard Output Drive:** Compatible with TTL inputs.  
- **Surface-Mount Package (SOIC-14):** Suitable for compact PCB designs.  

This information is based solely on the manufacturer's datasheet and technical documentation.

Application Scenarios & Design Considerations

Divide-By-Twelve Decade Counter

Alternative Part Number

  • CD74HC92E --: Same divide-by-twelve counter function in the 74-series family, CMOS version with comparable logic behavior and widely available.
  • MC74HC92ADG --: Direct functional equivalent divide-by-twelve counter from a different manufacturer and series, suitable drop-in for logic function.
  • 74HC92N --: Divide-by-twelve counter with same pin function in HC logic family, offered by an alternate supplier for sourcing flexibility.
  • SN74LS92N --: Same LS92 divide-by-twelve counter in a through-hole DIP package, electrically identical to the SOIC version and suitable when board space allows.
